ISSUE-312: forcedDisplay attribute is metadata so should be in ttm not tts namespace

forcedDisplay should be in ttm

forcedDisplay attribute is metadata so should be in ttm not tts namespace

State:
CLOSED
Product:
TTML IMSC 1.0
Raised by:
Nigel Megitt
Opened on:
2014-05-21
Description:
The description of tts:forcedDisplay [1] does not define any change in processing behaviour so it appears to be metadata and should therefore be moved to the ttm: namespace.

Incidentally the note in this section references "forcedDisplayMode" which is not defined anywhere.

Added recommended processor behavior in https://dvcs.w3.org/hg/ttml/diff/2720fa1fae9c/ttml-ww-profiles/ttml-ww-profiles.source.html

Pierre-Anthony Lemieux, 6 Jun 2014, 23:27:33

As agreed in TTWG meeting 12/6/2015 this needs a note added to the effect that the feature is likely not to be implemented in the same way in future versions of IMSC and TTML

Nigel Megitt, 12 Jun 2014, 15:05:11

There should also be a processor feature designator defined for processors that can process this attribute, for example #forcedDisplay.

Nigel Megitt, 13 Jun 2014, 16:15:57

Note added. See https://dvcs.w3.org/hg/ttml/raw-file/e78629db1b60/ttml-ww-profiles/ttml-ww-profiles.html

#forcedDisplay feature already defined in Annex B

Pierre-Anthony Lemieux, 17 Jun 2014, 03:35:31

Addressed in https://dvcs.w3.org/hg/ttml/diff/f994e1cbd7cd/ttml-ww-profiles/ttml-ww-profiles.source.html
